Revised -- NPP Gridded Estimates

Submitted by ORNL DAAC Staff on 2004-09-22

Data Set: NPP Multi-Biome: Gridded Estimates for Selected Regions Worldwide, 1989-2001, R[evision]2

Effective Date of Revision: September 22, 2004

Data Set Citation:

Zheng, D. L., S. D. Prince, and R. Wright. 2004. NPP Multi-Biome: Gridded Estimates for Selected Regions Worldwide, 1989-2001, R[evision]2. Data set. Available on-line [http://www.daac.ornl.gov] from the Oak Ridge National Laboratory Distributed Active Archive Center, Oak Ridge, Tennessee, U.S.A.

 

Revision Summary:

The Principal Investigator has provided new NPP estimates of better quality in reflecting the NPP gradient from SW to NE in  Sweden and Finland. The values of ANPP (anpp, Aboveground NPP (gC/m2/yr)) and TNPP (totnpp, Total NPP (gC/m2/yr)) were updated in the 82 grid cells for Sweden and Finland.

These new NPP estimates are discussed in the published paper:

Zheng, D., S.D. Prince, and T. Hame, 2004. Estimating net primary production of boreal forests in Finland and Sweden from field data and remote sensing. J. of Vegetation Science, 15: 161-170.

 

Data File Changes:

In the following data files:

NPP_Gridded_3654_cells_R2.csv

NPP_Gridded_2335_unique_cells_R2.csv

these two variables were updated for the 82 grid cells comprising Sweden and Finland.

anpp                 Aboveground NPP (gC/m2/yr)

totnpp              Total NPP (gC/m2/yr)

 

Data set documentation was updated to reflect the new data file names and to include the Zheng et al. 2004 reference.

 

Data User Action: If you downloaded and/or used the referenced data set from the ORNL DAAC on-line archive before September 29, 2004 you should download it again from the ORNL DAAC.

Data Set Availability: The revised data file and documentation are available from the ORNL DAAC [http://www.daac.ornl.gov/].  Please follow the data set links to download or order the file.
